This invention relates to an easel book construction for a ring book or loose leaf binder. In the prior art there are many forms of books incorporating easel supports on their binder constructions. The novelty in the present case relates to the way the easel ismade to cooperate with the metal part of the ring book.

The object of the invention is to make a more efficient ring binder and easel construction, with respect to the low cost of building in the easel element and to the specific way it works to make the structure more satisfactory from both the manufacturers and users standpoint.

An example of the way to practice the invention is disclosed by the drawings and their description. The example was made for a loose leaf cook book. It is used most conveniently when a housewife is most likely to have both hands occupied in her cooking work and when an easel cook book is the most useful kind.

In the drawings:

Fig. l is a perspective view of the binder provided with the easel in position for use;

Fig. 2 is a longitudinal section along the rivet line of the back panel but with the metal structure generally not sectioned;

Fig. 3 is a View of the ease] part of the structure separate from its binder part; and

Fig. 4 is a view looking at the back of the binder as it appears with the easel folded against the back panel.

In the example shown, the binder consists of the curved back panel I, covers 2 and 3 with hinges 6 along the sides of the back panel, the ring binder metal 4, riveted at '1 to the back panel. So far the structure is a routine type of three ring binder. To this type of binder shown there is added the easel 5. It is shown separately from the binder in Fig. 3.

A sheet metal plate 8 in single piece form is made with a lower portion 26, upstanding ears 2|, a wider portion 22, an upstanding end flange 23, and with spaced hinge eyes 24 on the upper edge of said flange. The portions 20 and 22 are curved to fit snugly against the upper portion and on the inside of back panel I. tion portion 28 is overlapped by the end portion of the ring binder metalfld, see Figs. 1 and 2,

in the assembly to be referred to later. Portion 2!] is of the same width as metal 4. The latter also extends upwardly a little to overlap a part of the wider portion 22, see Fig. 1. The cars 2| are bent in from opposite sides to clinch over the edges of the binder metal 4. In assembled position a hole 9 in portion 20 coincides with In this posi-,

2 Claims. (Cl. 28133) upper rivet I used to fasten the metal 4 to back panel I. Also in assembled position the flange portion 23 is upstanding at right angles. Its lower edge is curved as portions 20 and 22 are to conform to the curved back panel, but flange 23 is in a right angle plane to the plane of the book covers. The single upper rivet l, in fastening one end of metal 4 to back panel I, also fastens the sheet metal plate or stamping on the back panel as indicated in Fig. 2. When ears 2I closely confine metal 4, see Fig. 1, the metal stamping is held against any pivoting movement on the upper rivet I.

The easel arm is made of one piece of wire bent into general U form. Its connecting portion I I is curved to conform to curved back panel I. Its legs I2 are spaced by portion II to lie generally along the spaced hinges 6, preferably just inside the hinge lines. At the top of legs I2 the wires are bent into parallel hort portions I3, then inwardly on the axis of hinge eyes 24, see Fig. 3, and then into downwardly bent portions I4.

The preferred angles of these bends are indicated in Figs. 2 and 3. They determine the angle atwhich legs I2 can be turned away from the back panel before portions I4 will be stopped by contact with the inner side of flange 23. This angle of turning will determine the incline of the easel when the binder is put in the position of Fig. 1. The wire mentioned is stiff and is bent by tools at the factory.

From what has been said, it will be seen that the factory cost of supplying the easel to a threering binder is a low cost. The single sheet metal stamping and the single piece of stiff wire are all that is needed for the material of the easel. This small amount of material is shaped as shown in the drawings and as described above to make a specifically flne self-eifacing and efiicient easel which combines with the binder with these advantages. The appearance of the book is almost identical with or without the easel. That is to say, the easel construction has such a selfeiiacing characteristic that the book user is hardly conscious except by the function performed that a complete easel construction is built into the book. The wire legs I2 fold against the hinge lines 6 to be inconspicuous and only the portion I'I connecting the legs vary the lines of binder construction. Yet when the easel arm 5 is put in book supporting position, Fig. 1, the easel gives very eflicient support directly from the metal back bone of the binder. It is one which will not get out of order under hard usage in public use.

In manufacture it should be noted that themetal parts shown in Fig. 3 can be made and assembled as easel parts. When any routine binder of the type shown as the ring binder element needs an easel, the manufacturer can merely attach the assembly of Fig. 3 when he attaches the 'metal 4 to the back panel. The metal parts of the easel combine with the neta1 parts of the binder to supplement one another while the binder case,

back panel and hinged covers are of the same construction with or without the easel added.

The way to combine the easel and the ring binder will benefit the manufacturer and'the user.
